Villain relatively unknown although he seems straightforward TAGgish so far.

On the Turn: Should I bet more on the turn in these spots... like $6.50?

On the River: Can I profitably fire the river here to get him off TT-QQ or 98s etc...? And how much? Can I even get him to fold KJ/KQ with an overbet shove (I've seen a few coaches advocate this move in these spots against TAGs)?
